And good day to you! This week, I bring you the top twenty most blogged about tech videos of the week, for your viewing pleasure.

This really is the viral video with everything; Quark, protons, dimensions, collisions, particles... it could only be a rap about the Hadron Collider, of course! It's 27 miles of sexy science. But it there gals can impart even a few nuggets of wisdom about dark matter, it'll all be worth the humiliation.

Extra points if you can name the classic 'woo-yeah' sample throughout, and if you spot the salacious rubbing of a bumbag.

It has been a while since we had a juicy bit of time lapse, and this does the job just too well; the slow-mo demolition of a skyscraper called Daruma-otoshi in Japan. It's about the most elegant demolition you'll ever see.

Former astronaut Dr Edgar Mitchell - the sixth man to walk on the moon - tells a Kerrang DJ that there is life beyond our planet and that he has been briefed on extra-terrestrial happenings on this planet. The poor Kerrang DJ can't quite take it all in as Mitchell explains that although there's a huge amount of misinformation out there, Roswell was real, we have been visited already and plenty of incidents have been covered up by governments for more than 60 years.

He says there's a move towards disclosure - and we might get confirmation of that when all our UFO files area released in the next four years. But don't worry - he says the intent of aliens is not hostile. If it was, we'd be gone by now.
